Description

Shunt tripper is a tripper used for voltage source excitation; its own voltage can be independent from the voltage of main circuit. So, shunt tripper is an auxiliary of remote-control tripping, can disconnect circuit by remote, to liaison with fire alarm system. Can also remote control to trip off by Emergency stop button.

A standalone Miniature Circuit Breaker provides protection only against over-current and short circuit. When an Under-voltage / Over-voltage module is used it will trip the miniature circuit breaker or supplementary protector in the event the applied voltage across its coil terminals is out of the specified band.

In short, an under-voltage / over-voltage tripper is useful for protection against voltage dips and swells. Once supply recovers to normal, only then can the breaker be turned ON. This accessory provides a cost-effective and easy way to implement this solution.
